I am trying to filter features in a large Revit model by Category, Family, and then Family Type. Each Category has many Families which have many Family types. Using the Attribute Filter import feature on the first level (Category) is fine, but if you want to chain subsequent filters (Family and Family Type), the import brings in ALL attributes for the entire file, not just what is coming out of the respective Category filter outputs.

Is there a workaround for this? It would be so helpful to have a “local” setting where only feature attributes coming in to the secondary filter were selected.

Just to be clear, the import feature first gives me a choice to select from a list of feature types, but it still brings in more attributes than what actually is coming into the transformer. The resulting list turns the Attribute Filter into a massive object in the workspace.
